Supra stalls after sitting

2.5RHDsupra · 04-21-2010, 10:23 PM

Hey, My 1991 Toyota Supra TT seems to be acting funny.
ill get home from work at around 12 at night, and when i start the car up usually around 8 in the morning, its starts then idles under 1000 rpm.
then after about 10 seconds the rpms drop then the car stalls. i have to try to start my car about 3 times before it will not stall.
Any Ideas What Could Be Going wrong??

Potential problem areas that come to m mind are: ECU coolant temp sensor, Idle Speed Control Valve, cold start injector or the cold start time switch.

I'm moving this to the MKIII section where it belongs. Check the FAQ in that section for details on testing for diagnostic error codes and post back if you have any.
